KOCH, or STANTON, NEBRASKA TONGUE EXTENSION Application filed Februar 's, 1929. Serial No. 337,646.

The present invention relates to a tongue extension and has for its prime object to provide a device of this nature which is fastened upon any tongue used upon machinery drawn by horses, and is for the purpose of extending the tongue of said machinery to meet the requirements of the various lengths of horses so that the neck yoke attachment will not be a constant pull back and forward on a horse,

said extension being attached to' lengthen and to create a uniform and even pull upon the neck yoke of the horse.

Another very important object of the invention residesin the provision of an attachment of this nature which may be simple in its construction, strong and durable, in expensive to manufacture, easy to adjust, thoroughly efficient and reliable and otherwise well adaptedto the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the descrip tion proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: V

Figure 1 is a side elevation ofv a planter or the like, with my improved structure on the end-of the tongue,

Figure 2 is a longitudinal extension through the device and the forward end of the tongue,.

stantially on the line 3-3 of Figure 1,

Figure 4 is a perspective view of the extension member,

Figure 5is a perspective viewof the pin, and

Figure 6 is a perspective view of the neck yoke coupling.

Referring to the drawing in detail it will be seen that the numeral 5 denotes the tongue of a planter 6 or any other wheeled machine. The letter E denotes an extension member which is of U-shaped formation preferably constructed of strap iron and in the present instance comprises a pair of spaced parallel coextensive legplates 7 and a straight bight Figure 3 18 a transverse section taken sub- 7 plate 8 therebetween. The plates 7 are provided with registering openings 9 and registering openings .10. The 'free'extremities of the plates 7 straddle the. forward end of the tongue and bolts 11 pass through the openings 10 and through the tongue to secure the extension member E in place.

- A neck yoke 12 is mounted on a casting including elongated transverse loop members 14 connected together at their centers by integral portion 16. These loop members 14 and 15 receive the upper and lower plates 7 so that the casting may be slid along the extension member E with the shank 12 rising therefrom and rearward movement of the casting is limited by a stop pin 17 extended through a selected pair of openings 9 and accidental displacement of this stop pin is prevented by a cotter pin 18 on the bottom end thereof while the top end thereof has a laterally disposed head 19 to extend rearwardly.

The advantage of this extension device resides in the fact that adjustments may be madeto accommodate the needs of the horses and harness being used and create a uniform pull and thereby greatly assist the horses and not easily tire them when the tongue is not of the desired length.

All parts of the device are preferably made of steel and then to be used to extend wooden tongues although the same could be attached to steeltongues if the necessary holes for it are made therein.

It. is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The presentembodiment of the invention I has been disclosed in detail merely for. the purposes of exempliticationsince in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in thedetails of construction, in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, What I claim as neWis:

In combination with a tongue, a U-shaped extension member including a pair of coextensive spaced parallel leg plates connected by a bight plate at their forward ends, the

other ends of the plate extending a distance over and under the forward end ofotlie tongue, bolts securing the extension in place, a neck yoke pin formed on a casting, said casting including a pair of transverse elongated loop members for receiving the coextensive parallel plates so that the casting may slide thereon, said coextensive parallel plates having registering openings, and a stop pin for insertion therein to limit the movement of the casting rearWardly.

In testimony whereof I aflix my signature.
